In all cases the positive electrode is the same as in a conventional lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles.
The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.

A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The manufacturing steps include: grid manufacturing, paste manufacturing, plate manufacturing, plastic molding, and assembly. Of the 31 MJ of energy typically consumed in the production of a kilogram of lead–acid battery, about 9.2 MJ (30%) is associated with the manufacturing process.
Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.
The lead–acid battery has undergone many developments since its invention, but these have involved modifications to the materials or design, rather than to the underlying chemistry. In all cases, lead dioxide (PbO 2) serves as the positive active-material, lead (Pb) as the negative active-material, and sulfuric acid (H 2 SO 4) as the electrolyte.
Materials of Construction The main components of a lead–acid cell are lead dioxide at the positive electrode and sponge lead on the negative, each in contact with a current-collector made from lead alloy; an aqueous sulfuric acid electrolyte; a separator of porous insulating material; and a container that is generally made of polypropylene.
Currently, stationary energy-storage only accounts for a tiny fraction of the total sales of lead–acid batteries. Indeed the total installed capacity for stationary applications of lead–acid in 2010 (35 MW) was dwarfed by the installed capacity of sodium–sulfur batteries (315 MW), see Figure 13.13.
